Description

J-PARC E07 is the most ambitious and complex emulsion experiment to date investigating double hypernuclei with Hybrid emulsion method. The physics run at the K1.8 beam line in the J-PARC hadron experimental facility have been completed in 2017. The emulsion sheets are presently being analyzed with dedicated optical microscopes. Current statistics are estimated to be more 3 times than that of previous experiments. Quantitative data on the ΛΛ and ΞN interaction are being accumulated successfully via analysis of double Λ and Ξ hypernuclei. Multiple Ξ hypernucleus candidates suggests several features about Ξ hypernucleus that the identification efficiency of Ξ15C is significantly higher than other mode, many daughters of Ξ15C are identified as He or Be, and multiple bound states of Ξ− exist in the 14N nucleus. An analysis of X-ray spectroscopy of Ξ− hyperatoms are ongoing. (author)
